I'm self-taught in Greek, and have been a member of the B-Greek mailing list since 1996.
I am by no means an expert in Greek, but I am very interested in the Greek New Testament and the Greek language. So I like to hang out with the experts here and learn from them. I am also the list owner for B-Greek, which gives me a chance to do that.
In my day job, I'm probably best known as the editor of the XQuery and XPath specifications.
